After landing I’m usually instructed by Tower to exit the runway when able and to contact Ground.
Sometimes it’s done with a hand-off which I like more.
A few times now though I was already on an exit and hadn’t heard anything from Tower.
Do I request a frequency change, or do I just switch from Tower to Ground myself?
I don’t want to be rude and leave a frequency without permission but I also don’t want to bother Tower when he’s clearly busy, since it’s easy to switch yourself.
What’s the best way?
